The specified performance has been achieved with gentle, even plunger movements by means of distilled water at a constant (±0.5°C) room temperature between 20 and 25°C in accordance with EN ISO 8655.
Attention: The capacity of the instrument is reduced if the nut of the body is not loosened before autoclaving, and/or is tightened excessively during dosing.
